I have copied the /etc/sysctl.conf file from the working node to the failed node ad tried to restart the asm instance, but it is not working.

so i please take a look at the logs

As I seen in your log all devices have root privilege which is probably preventing Grid user to accessing physical disk and not able to start ASM instance which in turn make OCR devices inaccessible. Suggesting you to please assign appropriate privilege on the physical disks and retry to start CRS.

I have fixed it and here is how i done it. Actually it is very easy but it took 2 days for me to figure it out and the problem was my fello DB admin has changed
the sqlnet.ora file authnetication to none. Because of this the ASM instance had a trouble bring it up.

So what i did was, i commented out the autentication from the two sqlnet.ora files and it restarted the server, And everything worked perfectly
